Hey JIRA community :
In my board , I have defined 6 status (To do , in progress,In QA ,Blocked , In review , Done) and I will ask the team members update their assigned issues to the newest status and at last update to the "Done" status when the issues is completed.

My question is , how can I know the exact time of when a issue is changed to a specific status? For example , when it is updated to "Done" status.
